Expanding Rows for Unique Checkboxes

- by Marc Morgan

I was just recently given a project for my job to write a script that compares two mysql databases and print out information into an html table. Currently, I am trying to insert a checkbox by each individual's name and when selected, rows pertaining to that individual will expand underneath the person's name. I am combining javascript into my script to do this, although I really have no experience is it. The problem I am having is that when any checkbox is selected, all the rows for each individual is expanding instead of the rows pertaining only to the one individual selected. Here is the coding so far: <?php $link = mysql_connect ($server = "harris.lib.fit.edu", $username = "", $password = "") or die(mysql_error()); $db = mysql_select_db ("library-test") or die(mysql_error()); $ids = mysql_query("SELECT * FROM `ifc_studylog`") or die(mysql_error()); //not single quotes (tilda apostrophy) $x=0; $n=0; while($row = mysql_fetch_array( $ids )) { $tracksid1[$x] = $row['fitID']; $checkin[$x] = $row['checkin']; $checkout[$x] = $row['checkout']; $n++; $x++; } $names = mysql_query("SELECT * FROM `ifc_users`") or die(mysql_error()); //not single quotes (tilda apostrophy) $x=0; while($row = mysql_fetch_array( $names )) { $tracksnamefirst[$x] = $row['firstName']; $tracksnamesecond[$x] = $row['lastname']; $tracksid2[$x] = $row['fitID']; $tracksuser[$x] = $row['tracks']; $x++; } $x=0; foreach($tracksid2 as $comparename) { $chk = strval($x); ?> <script type='text/javascript' src='http://code.jquery.com/jquery-1.4.2.js'></script> <script type='text/javascript'> $(window).load(function () { $('.varx').click(function () { $('.text').toggle(this.checked); });}); </script> <?php echo '<td><input id = "<?=$chk?>" type="checkbox" class="varx" /></td>'; echo '<td align="center">'.$comparename.'</td>'; echo'<td align="center">'.$tracksnamefirst[$x].'</td>'; echo'<td align="center">'.$tracksnamesecond[$x].'</td>'; $z=0; foreach($tracksid1 as $compareid) { $HH=0; $MM =0; $SS =0; if($compareid == $comparename)// && $tracks==$tracksuser[$x]) { $SS = sprintf("%02s",(($checkout[$z]-$checkin[$z])%60)); $MM = sprintf("%02s",(($checkout[$z]-$checkin[$z])/60 %60)); $HH = sprintf("%02s",(($checkout[$z]-$checkin[$z])/3600 %24)); // echo'<td align="center">'.$HH.':'.$MM.':'.$SS.'</td>'; echo '</tr>'; echo '<tr>'; echo "<td id='txt' class='text' align='center' colspan='2' style='display:none'></td>"; echo "<td id='txt' class='text' align='center' style='display:none'>".$checkin[$z]."</td>"; echo '</tr>'; } echo '<tr>'; $z++; echo '</tr>'; } $x++; } } ?> Any Help is appreciated and sorry if I am too vague on the subject. The username and password is left off for security purposes.

How to Reuse Your Old Wi-Fi Router as a Network Switch

- by Jason Fitzpatrick

Just because your old Wi-Fi router has been replaced by a newer model doesn’t mean it needs to gather dust in the closet. Read on as we show you how to take an old and underpowered Wi-Fi router and turn it into a respectable network switch (saving your $20 in the process). Image by mmgallan. Why Do I Want To Do This? Wi-Fi technology has changed significantly in the last ten years but Ethernet-based networking has changed very little. As such, a Wi-Fi router with 2006-era guts is lagging significantly behind current Wi-Fi router technology, but the Ethernet networking component of the device is just as useful as ever; aside from potentially being only 100Mbs instead of 1000Mbs capable (which for 99% of home applications is irrelevant) Ethernet is Ethernet. What does this matter to you, the consumer? It means that even though your old router doesn’t hack it for your Wi-Fi needs any longer the device is still a perfectly serviceable (and high quality) network switch. When do you need a network switch? Any time you want to share an Ethernet cable among multiple devices, you need a switch. For example, let’s say you have a single Ethernet wall jack behind your entertainment center. Unfortunately you have four devices that you want to link to your local network via hardline including your smart HDTV, DVR, Xbox, and a little Raspberry Pi running XBMC. Instead of spending $20-30 to purchase a brand new switch of comparable build quality to your old Wi-Fi router it makes financial sense (and is environmentally friendly) to invest five minutes of your time tweaking the settings on the old router to turn it from a Wi-Fi access point and routing tool into a network switch–perfect for dropping behind your entertainment center so that your DVR, Xbox, and media center computer can all share an Ethernet connection. What Do I Need? For this tutorial you’ll need a few things, all of which you likely have readily on hand or are free for download. To follow the basic portion of the tutorial, you’ll need the following: 1 Wi-Fi router with Ethernet ports 1 Computer with Ethernet jack 1 Ethernet cable For the advanced tutorial you’ll need all of those things, plus: 1 copy of DD-WRT firmware for your Wi-Fi router We’re conducting the experiment with a Linksys WRT54GL Wi-Fi router. The WRT54 series is one of the best selling Wi-Fi router series of all time and there’s a good chance a significant number of readers have one (or more) of them stuffed in an office closet. Even if you don’t have one of the WRT54 series routers, however, the principles we’re outlining here apply to all Wi-Fi routers; as long as your router administration panel allows the necessary changes you can follow right along with us. A quick note on the difference between the basic and advanced versions of this tutorial before we proceed. Your typical Wi-Fi router has 5 Ethernet ports on the back: 1 labeled “Internet”, “WAN”, or a variation thereof and intended to be connected to your DSL/Cable modem, and 4 labeled 1-4 intended to connect Ethernet devices like computers, printers, and game consoles directly to the Wi-Fi router. When you convert a Wi-Fi router to a switch, in most situations, you’ll lose two port as the “Internet” port cannot be used as a normal switch port and one of the switch ports becomes the input port for the Ethernet cable linking the switch to the main network. This means, referencing the diagram above, you’d lose the WAN port and LAN port 1, but retain LAN ports 2, 3, and 4 for use. If you only need to switch for 2-3 devices this may be satisfactory. However, for those of you that would prefer a more traditional switch setup where there is a dedicated WAN port and the rest of the ports are accessible, you’ll need to flash a third-party router firmware like the powerful DD-WRT onto your device. Doing so opens up the router to a greater degree of modification and allows you to assign the previously reserved WAN port to the switch, thus opening up LAN ports 1-4. Even if you don’t intend to use that extra port, DD-WRT offers you so many more options that it’s worth the extra few steps. Preparing Your Router for Life as a Switch Before we jump right in to shutting down the Wi-Fi functionality and repurposing your device as a network switch, there are a few important prep steps to attend to. First, you want to reset the router (if you just flashed a new firmware to your router, skip this step). Following the reset procedures for your particular router or go with what is known as the “Peacock Method” wherein you hold down the reset button for thirty seconds, unplug the router and wait (while still holding the reset button) for thirty seconds, and then plug it in while, again, continuing to hold down the rest button. Over the life of a router there are a variety of changes made, big and small, so it’s best to wipe them all back to the factory default before repurposing the router as a switch. Second, after resetting, we need to change the IP address of the device on the local network to an address which does not directly conflict with the new router. The typical default IP address for a home router is 192.168.1.1; if you ever need to get back into the administration panel of the router-turned-switch to check on things or make changes it will be a real hassle if the IP address of the device conflicts with the new home router. The simplest way to deal with this is to assign an address close to the actual router address but outside the range of addresses that your router will assign via the DHCP client; a good pick then is 192.168.1.2. Once the router is reset (or re-flashed) and has been assigned a new IP address, it’s time to configure it as a switch. Basic Router to Switch Configuration If you don’t want to (or need to) flash new firmware onto your device to open up that extra port, this is the section of the tutorial for you: we’ll cover how to take a stock router, our previously mentioned WRT54 series Linksys, and convert it to a switch. Hook the Wi-Fi router up to the network via one of the LAN ports (consider the WAN port as good as dead from this point forward, unless you start using the router in its traditional function again or later flash a more advanced firmware to the device, the port is officially retired at this point). Open the administration control panel via web browser on a connected computer. Before we get started two things: first, anything we don’t explicitly instruct you to change should be left in the default factory-reset setting as you find it, and two, change the settings in the order we list them as some settings can’t be changed after certain features are disabled. To start, let’s navigate to Setup ->Basic Setup. Here you need to change the following things: Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable Save with the “Save Settings” button and then navigate to Setup -> Advanced Routing: Operating Mode: Router This particular setting is very counterintuitive. The “Operating Mode” toggle tells the device whether or not it should enable the Network Address Translation (NAT) feature. Because we’re turning a smart piece of networking hardware into a relatively dumb one, we don’t need this feature so we switch from Gateway mode (NAT on) to Router mode (NAT off). Our next stop is Wireless -> Basic Wireless Settings: Wireless SSID Broadcast: Disable Wireless Network Mode: Disabled After disabling the wireless we’re going to, again, do something counterintuitive. Navigate to Wireless -> Wireless Security and set the following parameters: Security Mode: WPA2 Personal WPA Algorithms: TKIP+AES WPA Shared Key: [select some random string of letters, numbers, and symbols like JF#d$di!Hdgio890] Now you may be asking yourself, why on Earth are we setting a rather secure Wi-Fi configuration on a Wi-Fi router we’re not going to use as a Wi-Fi node? On the off chance that something strange happens after, say, a power outage when your router-turned-switch cycles on and off a bunch of times and the Wi-Fi functionality is activated we don’t want to be running the Wi-Fi node wide open and granting unfettered access to your network. While the chances of this are next-to-nonexistent, it takes only a few seconds to apply the security measure so there’s little reason not to. Save your changes and navigate to Security ->Firewall. Uncheck everything but Filter Multicast Firewall Protect: Disable At this point you can save your changes again, review the changes you’ve made to ensure they all stuck, and then deploy your “new” switch wherever it is needed. Advanced Router to Switch Configuration For the advanced configuration, you’ll need a copy of DD-WRT installed on your router. Although doing so is an extra few steps, it gives you a lot more control over the process and liberates an extra port on the device. Hook the Wi-Fi router up to the network via one of the LAN ports (later you can switch the cable to the WAN port). Open the administration control panel via web browser on the connected computer. Navigate to the Setup -> Basic Setup tab to get started. In the Basic Setup tab, ensure the following settings are adjusted. The setting changes are not optional and are required to turn the Wi-Fi router into a switch. WAN Connection Type: Disabled Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable In addition to disabling the DHCP server, also uncheck all the DNSMasq boxes as the bottom of the DHCP sub-menu. If you want to activate the extra port (and why wouldn’t you), in the WAN port section: Assign WAN Port to Switch [X] At this point the router has become a switch and you have access to the WAN port so the LAN ports are all free. Since we’re already in the control panel, however, we might as well flip a few optional toggles that further lock down the switch and prevent something odd from happening. The optional settings are arranged via the menu you find them in. Remember to save your settings with the save button before moving onto a new tab. While still in the Setup -> Basic Setup menu, change the following: Gateway/Local DNS : [IP address of primary router, e.g. 192.168.1.1] NTP Client : Disable The next step is to turn off the radio completely (which not only kills the Wi-Fi but actually powers the physical radio chip off). Navigate to Wireless -> Advanced Settings -> Radio Time Restrictions: Radio Scheduling: Enable Select “Always Off” There’s no need to create a potential security problem by leaving the Wi-Fi radio on, the above toggle turns it completely off. Under Services -> Services: DNSMasq : Disable ttraff Daemon : Disable Under the Security -> Firewall tab, uncheck every box except “Filter Multicast”, as seen in the screenshot above, and then disable SPI Firewall. Once you’re done here save and move on to the Administration tab.

Building services with .Net Part 1

- by Allan Rwakatungu

On the 26th of May 2010 , I made a presentation to the .NET user group meeting (thanks to Malisa Ncube for organizing this event every month … ). If you missed my presentation , we talked about why we should all be building services … better still using the .NET framework. This blog post is an introduction to services , why you would want to build services and how you can build services using the .NET framework. What is a service? OASIS defines service as "a mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description." [1]. If the above definition sounds to academic , you can also define a service as loosely coupled units of functionality that have no calls to each other embedded in the. Instead of services embedding calls to each other in their service code they use defined protocols that describe how services pass and parse messages. This is a good way to think about services if you’re from an objected oriented background. While in object oriented programming functions make calls to each other, in service oriented programming, functions pass messages between each other. Why would you want to use services? 1. If your enterprise architecture looks like this Services are the building blocks for SOA . With SOA you can move away from the sphaggetti infrastructure that is common in most enterprises. The complexity or lack of visibility of the integration points in your enterprises makes it difficult and costly to implement new initiatives and changes into the business - and even impossible in some cases - as it is not possible to identify the impact a change in one system might have to other systems. With services you can move to an architecture like this Your building blocks from Spaghetti infrastructure to something that is more well-defined and manageable to achieve cost efficiency and not least business agility - enabling you to react to changes in the market with speed and achieve operational efficiency and control are services. 2. If you want to become the Gates or Zuckerburger. Have you heard about Web 2.0 ? Mashups? Software as a service (SAAS) ? Cloud computing ? They all offer you the opportunity to have scalable but low cost business models and they built using services. Some of my favorite companies that leverage services for their business models include https://www.salesforce.com/ (cloud CRM) http://www. twitter.com (more people use twitter clients built by 3rd parties than their official clients) http://www.kayak.com/ (compares data from other travel sites to give information to users in one location) Services with the .NET framework If you are a .NET developer and you want to develop services, Windows Communication Framework (WCF) is the tool for you. WCF is Microsoft’s unified programming model (service model) for building service oriented applications. ( Before .NET 3.0 you had several models for programming services in .NET including .NET remoting, Web services (ASMX), COM +, Microsoft Messaging queuing (MSMQ) etc, after .NET 3.0 the programming model was unified into one i.e. WCF ). Windows Communication Framework (WCF) provides you 1. An Software Development Kit (SDK) for creating SOA applications 2. A runtime for running services on the Windows platform Why should you use Windows Communication Foundation if you’re programming services? 1. It supports interoperable and open standards e.g. WS* protocols for programming SOAP services 2. It has a unified programming model. Whether you use TCP or Http or Pipes or transmitting using Messaging Queues, programmers need to learn just one way to program. Previously you had .NET remoting, MSMQ, Web services, COM+ and they were all done differently 3. Productive programming model You don’t have to worry about all the plumbing involved to write services. You have a rich declarative programming model to add stuff like logging, transactions, and reliable messages in-built in the Windows Communication Framework. Understanding services in WCF The basic principles of WCF are as easy as ABC A – Address This is where the service is located B- Binding This describes how you communicate with the service e.g. Use TCP, HTTP or both. How to exchange security information with the service etc. C – Contract This defines what the service can do. E.g. Pay water bill, Make a phone call A - Addresses In WCF, an address is a combination of transport, server name, port and path Example addresses may include http://localhost:8001 net.tcp://localhost:8002/MyService net.pipe://localhost/MyPipe net.msmq://localhost/private/MyService net.msmq://localhost/MyService B- Binding There are numerous ways to communicate with services , different ways that a message can be formatted/sent/secured, that allows you to tailor your service for the compatibility/performance you require for your solution. Transport You can use HTTP TCP MSMQ , Named pipes, Your own custom transport etc Message You can send a plain text binary, Message Transmission Optimization Mechanism (MTOM) message Communication security No security Transport security Message security Authenticating and authorizing callers etc Behaviour You service can support Transactions Be reliable Use queues Support ajax etc C - Contract You define what your service can do using Service contracts :- Define operations that your service can do, communications and behaviours Data contracts :- Define the messages that are passed from and into your service and how they are formatted Fault contracts :- Defines errors types in your service As an example, suppose your service service shows money. You define your service contract using a interface [ServiceContract] public interface IShowMeTheMoney { [OperationContract] Money Show(); } You define the data contract by annotating a class it with the Data Contract attribute and fields you want to pass in the message as Data Members. (Note:- In the latest versions of WCF you dont have to use attributes if you passing all the objects properties in the message) [DataContract] public Money { [DataMember] public string Currency { get; set; } [DataMember] public Decimal Amount { get; set; } public string Comment { get; set; } } Features of Windows Communication Foundation Windows Communication Foundation is not only simple but feature rich , offering you several options to tweak your service to fit your business requirements. Some of the features of WCF include 1. Workflow services You can combine WCF with Windows WorkFlow Foundation (WWF) to write workflow type services 2. Control how your data (messages) are transferred and serialized e.g. you can serialize your business objects as XML or binary 3. control over session management , instance creation and concurrency management without writing code if you like 4. Queues and reliable sessions. You can store messages from the sending client and later forward them to the receiving application. You can also guarantee that messages will arrive at their destincation. 5.Transactions: You can have different services participate in a transaction operations that can be rolled back if needed 6. Security. WCF has rich features for authorization and authentication as well as keep audit trails 7. Web programming model. WCF allows developers to expose services as non SOAP endpoints 8. Inbuilt features that you can use to write JSON and services that support AJAX applications And lots more In my next blog I will show you how you can use WCF features to write a real world business service.

Resize Image thru Slider in Silverlight

- by Sayre Collado

Hello Guys, I've been playing with slider on silverlight. Now the result is this, a simple resizing image thru slider. The Image below is the default size of my sample. And the second Image below are the result when the slider slide to right and top. The xaml layout are very simple: <Slider Minimum="80" Maximum="238" Height="23" HorizontalAlignment="Center" Name="sldBottom" Width="246" Margin="27,226,27,1" /> <Slider Height="212" Minimum="80" Maximum="209" Name="sldRight" Width="28" Orientation="Vertical" Margin="271,9,1,29" /> <Image HorizontalAlignment="Center" Name="image1" Stretch="Fill" VerticalAlignment="Center" Source="/GBLOgs2;component/Images/logosai.JPG" Height="{Binding ElementName=sldRight,Path=Value}" Width="{Binding ElementName=sldBottom,Path=Value}" /> The Image1 Height are depending to the maximum value of sldRight and its value same with the situation of Image1 Width. The Image1 Height/Width = {Binding ElementName="NAME OF THE SLIDER", Path="THE VALUE OF SLIDER"}. When you slide the slider the image will resize. And thats all. Happy Programming.

Ubuntu 14.04: After login, top- and sidepanel don't load and system settings don't open

- by Löwe Simon

I have Ubuntu 14.04 on a Medion Erazer with the Nvidia GTX570M card. At first, while I had not installed the last nvidia driver, each time I would try to suspend my pc it would freeze frame on the login. Once I managed to install the nvidia drivers, everything seemed to work up until I noticed that suddenly the system settings would not open anymore. I then rebooted my pc, but when I logged in I just end up with my cursor but no top panel or side pannel. Thankfully, I had installed the gnome desktops which works, except for the fact the system settings do not open also in the gnome desktop. I have tried following: Problems after upgrading to 14.04 (only background and pointer after login) except for reinstalling nvidia, since then I would be back at square one with suspend not working. When I try to launch system settings through the terminal, I get: simon@simon-X681X:~$ unity-control-center libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast (unity-control-center:2806): Gdk-ERROR **: The program 'unity-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 229 error_code 16 request_code 155 (GLX) minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I know the 2 problems seem unrelated, but since they occured together, I am wondering if that is really the case. Your help is much appreciated, Simon

Flash Technology Can Revolutionize your IT Infrastructure

- by kimberly.billings

A recent article in the Data Center Journal written by Mark Teter outlines how flash is becoming a disruptive technology in the data center and how it will soon replace HDDs in the storage hierarchy. As Teter explains, the drivers behind this trend are lower cost/performance and power savings; flash is over 100x faster for reads than the fastest HDD, and while it is expensive, it can produce dramatic reductions in the cost of performance as measured in Input/Outputs per second (IOPS). What's more, flash consumes 1/5th the power of HDD, so it's faster AND greener. Teter writes, "when appropriately used, flash turns the current economics of IT performance on its head. That's disruptive." Exadata Smart Flash Cache in the Sun Oracle Database Machine makes intelligent use of flash storage to deliver extreme performance for OLTP and mixed workloads. It intelligently caches data from the Oracle Database replacing slow mechanical I/O operations to disk with very rapid flash memory operations. Exadata Smart Flash Cache is the fundamental technology of the Sun Oracle Database Machine that enables the processing of up to 1 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 50 GB/second.

HTG Explains: Do Non-Windows Platforms Like Mac, Android, iOS, and Linux Get Viruses?

- by Chris Hoffman

Viruses and other types of malware seem largely confined to Windows in the real world. Even on a Windows 8 PC, you can still get infected with malware. But how vulnerable are other operating systems to malware? When we say “viruses,” we’re actually talking about malware in general. There’s more to malware than just viruses, although the word virus is often used to talk about malware in general. Why Are All the Viruses For Windows? Not all of the malware out there is for Windows, but most of it is. We’ve tried to cover why Windows has the most viruses in the past. Windows’ popularity is definitely a big factor, but there are other reasons, too. Historically, Windows was never designed for security in the way that UNIX-like platforms were — and every popular operating system that’s not Windows is based on UNIX. Windows also has a culture of installing software by searching the web and downloading it from websites, whereas other platforms have app stores and Linux has centralized software installation from a secure source in the form of its package managers. Do Macs Get Viruses? The vast majority of malware is designed for Windows systems and Macs don’t get Windows malware. While Mac malware is much more rare, Macs are definitely not immune to malware. They can be infected by malware written specifically for Macs, and such malware does exist. At one point, over 650,000 Macs were infected with the Flashback Trojan. [Source] It infected Macs through the Java browser plugin, which is a security nightmare on every platform. Macs no longer include Java by default. Apple also has locked down Macs in other ways. Three things in particular help: Mac App Store: Rather than getting desktop programs from the web and possibly downloading malware, as inexperienced users might on Windows, they can get their applications from a secure place. It’s similar to a smartphone app store or even a Linux package manager. Gatekeeper: Current releases of Mac OS X use Gatekeeper, which only allows programs to run if they’re signed by an approved developer or if they’re from the Mac App Store. This can be disabled by geeks who need to run unsigned software, but it acts as additional protection for typical users. XProtect: Macs also have a built-in technology known as XProtect, or File Quarantine. This feature acts as a blacklist, preventing known-malicious programs from running. It functions similarly to Windows antivirus programs, but works in the background and checks applications you download. Mac malware isn’t coming out nearly as quick as Windows malware, so it’s easier for Apple to keep up. Macs are certainly not immune to all malware, and someone going out of their way to download pirated applications and disable security features may find themselves infected. But Macs are much less at risk of malware in the real world. Android is Vulnerable to Malware, Right? Android malware does exist and companies that produce Android security software would love to sell you their Android antivirus apps. But that isn’t the full picture. By default, Android devices are configured to only install apps from Google Play. They also benefit from antimalware scanning — Google Play itself scans apps for malware. You could disable this protection and go outside Google Play, getting apps from elsewhere (“sideloading”). Google will still help you if you do this, asking if you want to scan your sideloaded apps for malware when you try to install them. In China, where many, many Android devices are in use, there is no Google Play Store. Chinese Android users don’t benefit from Google’s antimalware scanning and have to get their apps from third-party app stores, which may contain infected copies of apps. The majority of Android malware comes from outside Google Play. The scary malware statistics you see primarily include users who get apps from outside Google Play, whether it’s pirating infected apps or acquiring them from untrustworthy app stores. As long as you get your apps from Google Play — or even another secure source, like the Amazon App Store — your Android phone or tablet should be secure. What About iPads and iPhones? Apple’s iOS operating system, used on its iPads, iPhones, and iPod Touches, is more locked down than even Macs and Android devices. iPad and iPhone users are forced to get their apps from Apple’s App Store. Apple is more demanding of developers than Google is — while anyone can upload an app to Google Play and have it available instantly while Google does some automated scanning, getting an app onto Apple’s App Store involves a manual review of that app by an Apple employee. The locked-down environment makes it much more difficult for malware to exist. Even if a malicious application could be installed, it wouldn’t be able to monitor what you typed into your browser and capture your online-banking information without exploiting a deeper system vulnerability. Of course, iOS devices aren’t perfect either. Researchers have proven it’s possible to create malicious apps and sneak them past the app store review process. [Source] However, if a malicious app was discovered, Apple could pull it from the store and immediately uninstall it from all devices. Google and Microsoft have this same ability with Android’s Google Play and Windows Store for new Windows 8-style apps. Does Linux Get Viruses? Malware authors don’t tend to target Linux desktops, as so few average users use them. Linux desktop users are more likely to be geeks that won’t fall for obvious tricks. As with Macs, Linux users get most of their programs from a single place — the package manager — rather than downloading them from websites. Linux also can’t run Windows software natively, so Windows viruses just can’t run. Linux desktop malware is extremely rare, but it does exist. The recent “Hand of Thief” Trojan supports a variety of Linux distributions and desktop environments, running in the background and stealing online banking information. It doesn’t have a good way if infecting Linux systems, though — you’d have to download it from a website or receive it as an email attachment and run the Trojan. [Source] This just confirms how important it is to only run trusted software on any platform, even supposedly secure ones. What About Chromebooks? Chromebooks are locked down laptops that only run the Chrome web browser and some bits around it. We’re not really aware of any form of Chrome OS malware. A Chromebook’s sandbox helps protect it against malware, but it also helps that Chromebooks aren’t very common yet. It would still be possible to infect a Chromebook, if only by tricking a user into installing a malicious browser extension from outside the Chrome web store. The malicious browser extension could run in the background, steal your passwords and online banking credentials, and send it over the web. Such malware could even run on Windows, Mac, and Linux versions of Chrome, but it would appear in the Extensions list, would require the appropriate permissions, and you’d have to agree to install it manually. And Windows RT? Microsoft’s Windows RT only runs desktop programs written by Microsoft. Users can only install “Windows 8-style apps” from the Windows Store. This means that Windows RT devices are as locked down as an iPad — an attacker would have to get a malicious app into the store and trick users into installing it or possibly find a security vulnerability that allowed them to bypass the protection. Malware is definitely at its worst on Windows. This would probably be true even if Windows had a shining security record and a history of being as secure as other operating systems, but you can definitely avoid a lot of malware just by not using Windows. Of course, no platform is a perfect malware-free environment. You should exercise some basic precautions everywhere. Even if malware was eliminated, we’d have to deal with social-engineering attacks like phishing emails asking for credit card numbers. Image Credit: stuartpilbrow on Flickr, Kansir on Flickr

I want to have simple 45° slopes in my tile based platformer, however I just cant seem to get the algorithm down. Please take a look at the code and video, maybe I'm missing the obvious? //collisionRectangle is the collision rectangle of the player with //origin at the top left and width and height //wantedPosition is the new position the player will be set to. //this is determined elsewhere by checking the bottom center point of the players rect if(_leftSlope || _rightSlope) { //Test bottom center point var calculationPoint = new Vector2(collisionRectangle.Center.X, collisionRectangle.Bottom); //Get the collision rectangle of the tile, origin is top-left Rectangle cellRect = _tileMap.CellWorldRectangle( _tileMap.GetCellByPixel(calculationPoint)); //Calculate the new Y coordinate depending on if its a left or right slope //CellSize = 8 float newY = _leftSlope ? (calculationPoint.X % CellSize) + cellRect.Y : (-1 * (calculationPoint.X % CellSize) - CellSize) + cellRect.Y; //reset variables so we dont jump in here next frame _leftSlope = false; _rightSlope = false; //now change the players Y according to the difference of our calculation wantedPosition.Y += newY - calculationPoint.Y; } Video of what it looks like: http://youtu.be/EKOWgD2muoc

Every Microsoft oriented infrastructure in today's enterprises will depend largely on the active directory version built by Microsoft. It is the foundation stone on which all other products (Exchange, update services, office communicator, the system center family, etc) rely on to get their information. And that is just looking at it from an infrastructure perspective. A well designed and implemented Active Directory implementation makes life for IT personnel and user alike a lot easier. Centralised management and the abilities opened up by having it in place are ample. But what is Active Directory Domain Services? We can look at ADDS as a centralised directory containing all objects your infrastructure runs on in one way or another. Since it is a Microsoft product you'll obviously not be seeing linux or mac clients listed in here (exceptions exist) but in general we can say it contains everything your company has in place in one form or another. The domain name services. The domain naming service (or DNS for short) is a service which translates IP address (the identifiers for each computer in your domain) into readable and easy to understand names. This service is a prequisite for ADDA to work and having wrong record in a DNS server will make any ADDS service fail. Generally speaking a DNS service will be run on the same server as the ADDS service but it is worth wile to remember that this is not necessary. You could, for example, run your DNS services on a linux box (which would need special preparing to host an ADDS integrated DNS zone) and run the ADDS service of another box… Where to start? If the aim is to put in place a first time implementation of ADDS in your enterprise there are plenty of things to consider depending on what you are going to do in the long run. Great care has to be taken when first designing and implementing as having it set up wrong will cause a headache down the line. It is for that reason that I like to start building from the bottom up and start with a generic installation of ADDS (which will still differ for every client) and make it adaptable for future services which can hook in to the existing environment. Adapting existing environments is out of scope for this document (and series) although it is possible to take the pointers and change your existing environment to run in a smoother manor. Take great care when changing things as one small slip of the hand can give you a forest wide failure… Whenever starting with an ADDS deployment I ask the client the following questions: What are your long term plans and goals? How flexible do you want it? Are you currently linux heavy and want to keep this or can we go for an all Microsoft design? Those three questions should give some sort of indicator what direction can be taken and if the client has thought about some things themselves :). The technical side of things What is next to consider is what kind of infrastructure is already in place. For these series I'll keep it simple and introduce some general concepts without going in to depth on integrating ADDS with other DNS services. Building from the ground up means we need to consider our layers on which our infrastructure will rely. In my view that goes as follows: Network (WAN/LAN links and physical sites DNS Namespacing All in one domain or split up in different domains/forests? Security (both for ADDS and physical sites) The network side of things Looking at how the network is currently set up can potentially teach us a large deal about the client. Do they have multiple physical site? What network speeds exist between these sites, etc… Depending on this information we will design our site links (which controls replication) in future stages. DNS Namespacing Maybe the single most intresting thing to know is what the domain will be named (ADDS will need a DNS domain with the same name) and where this will be hosted. Note that active directory can be set up with a singe name (aka contoso instead of contoso.com) but it is highly recommended to never do this. If you do end up with a domain like that for some reason there will be a lot of services that are going to give you good grief in the future (exchange being one of them). So one of the best practises would be always to use a double name (contoso.com or contoso.lan for example). Internal namespace A single namespace is just what it sounds like. You have a DNS domain which is different internally from what the client has as an external namespace. f.e. contoso.com as an external name (out on the internet) and contoso.lan on the internal network. his setup is has its advantages in that you have more obscurity from the internet in the DNS side of this but it will require additional work to publish services to the web. External namespace Quite like the internal namespace only here you do not differ the internal namespace of the company from what is known on the internet. In this implementation you would host your own DNS servers for the external domain inside the network. Or in other words, any external computer doing a DNS lookup would contact your internal DNS server for the resolution. Generally speaking this set up is a bad idea from the security side of things. Split DNS Whilst using an external namespace design is fairly easy it involves a lot of security risks. Opening up you ADDS DSN servers for lookups exposes your entire network to the internet and should be avoided at any cost. And that is where the "split DNS" design comes in. In this setup up would still have the same namespace internally and externally but you would be using different DNS servers for lookups on the external network who have no records of your internal resources unless you explicitly publish them. All in one or not? In determining your active directory design you can look at the following possibilities: Single forest, Single domain Single forest, multiple domains Multiple forests, multiple domains I've listed the possibilities for design in increasing order of administrative magnitude. Microsoft recommends trying to use a single forest, single domain in as much situations as possible. It is, however, always possible that you require your services to be seperated from your users in a resource forest with trusts set up between the different forests. To start out I would go with the single forest design to avoid complexity unless there are strict requirements to have multiple forests. Security What kind of security is required on the domain and does this reflect the physical security on the sites? Not every client can afford to have a domain controller in a secluded server room on every site and it is exactly for that reason that Microsoft introduced the RODC (read only domain controller). A RODC is a domain controller that has been limited in functionality, in essence it will only cache the data you explicitly tell it to cache and in the case of a DC compromise (it being stolen) only a limited number of accounts will need to be affected. Th- Th- Th- That’s all folks! Well at least for now! In future editions of this series we’ll be walking through the different task that need to be done and the thought which needs to be put in to it. But for all editions we’ll be going from the concept of running a single forest, single domain with a split DNS setup… See you next time!

C # - a variable using the Encrypt md5

- by Guilherme Cardoso

When we are dealing with more sensitive data and important as a keyword, it is not appropriate at all stores them in database without encrypting for security reasons. For this we use MD5 MD5 is an algorithm that allow us to encript an string, but doesn't leave us desencrypt it (not sure if it is already possible, but at least I know there are many databases already having a record). The method below will return us a variable encrypted with md5. For example: md5_encriptar (pontonetpt.com "); The result will be: 34efe85d338075834ad41803eb08c0df This way we save tthese encrypted data into a database, and then to make comparisons we often use the method to compare with the records kept. public string md5_encrypt(string md5) { System.Security.Cryptography.MD5CryptoServiceProvider x = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] bs = System.Text.Encoding.UTF8.GetBytes(md5); bs = x.ComputeHash(bs); System.Text.StringBuilder s = new System.Text.StringBuilder(); foreach (byte b in bs) { s.Append(b.ToString("x2").ToLower()); } string password = s.ToString(); return password; }

Google play game services and Facebook integration in one game

- by Ineentho

We are creating a cross platform game for iOS and Android. We have thought about how and with which services we should integrate achievements and scoreboards with. For the iOS part, we are pretty sure that this how we want to do, in order from when the user opens the app for the first time: Connect with Game Center (Should be automatic, the user shouldn't even notice?) We will also get the players nickname for public scoreboards here. Ask if the user wants to connect with Facebook so that we can compare the players highscores with their friends. We could add Google play game services there as well, but I don't feel like that adds anything to the experience for the end user. Now comes the tricky part: Android We thought that we could do just like for iOS, except that we replace Game Center with Google Play Game Services. However, unlike Game Center, Game Services will ask the user to log in to their Google+ account and allow us to access their account. So now, what we have is a double login, first with Google+ and then with Facebook. What will users think about that? Should we scrap Play Services entirely and just ask the user for a nickname within our app and user Facebook for achievements?

5 Design Tricks Facebook Uses To Affect Your Privacy Decisions

- by Jason Fitzpatrick

If you feel like Facebook increasingly has fewer and fewer options to reject applications and organization access to your private information, you’re not imagining it. Here are five ways Facebook’s design choices in the App Center have minimized your choices over time. Over at TechCrunch they have a guest post by Avi Charkham highlighting five ways recent changes to the Facebook App Center put privacy settings on the back burner. In regard to the comparison seen in the image above, for example, he writes: #1: The Single Button Trick In the old design Facebook used two buttons – “Allow” and “Don’t Allow” – which automatically led you to make a decision. In the new App Center Facebook chose to use a single button. No confirmation, no decisions to make. One click and, boom, your done! Your information was passed on to the app developers and you never even notice it. Hit up the link below to check out the other four redesign choices that minimize the information about privacy and data usage you see and maximize the click-through and acceptance rate for apps.

Access Control and Accessibility in Oracle IRM 11g

- by martin.abrahams

A recurring theme you'll find throughout this blog is that IRM needs to balance security with usability and manageability. One of the innovations in Oracle IRM 11g typifies this, as we have introduced a new right that may be included in any role - Accessibility. When creating or modifying a role, you simply select Accessibility along with Open, Print, Edit or whatever rights you want to include in the role. You might, for example, have parallel roles of Reader and Reader with Accessibility and Contributor and Contributor with Accessibility. The effect of the Accessibility right is to relax some of the protection of content in use such that selected users can use accessibility tools. For example, a user with the Accessibility right would be able to use the screen magnification tool, which IRM would ordinarily prevent because it involves screen capture. This new right makes it easy for you to apply security to documents yet, subject to suitable approval processes, cater for the fact that a subset of users might be disproportionately inconvenienced by some of the normal usage constraints. Rather than make those users put up with the restrictions, or perhaps exempt them from using sealed documents altogether, this new right allows you to accommodate them in a controlled manner, and to balance security with corporate accessibility goals.
